I guess a better way of describing the method I'm familiar with is that it aims to quiet the mind so that the nature of self (self enquiry - atma Vichara) enquired into and realised - That's basically Advaita Vedanta (I believe).
Additionally, that in order to quiet the mind fully, the powerful thought driving desires need to be released. That these desires, (attachments and aversions) are inherently what make up our mental limitations that are present in our life. That if we resided in a monastery these limitations may not be obvious to us.
As you have said though, and as I noted in another thread, there seems to be a notion of ultimate self in Advaita that's perhaps not pressent in Buddhism.
I am learning that Buddhism comes at things from a different angle. Almost not making the assumption self enquiry makes by instead gaining insight into the workings of the mind. I have much more to learn I think.
In terms of "in spite of what you say" comment, sorry if it was confrontational. I guess I meant that I shouldn't take the Buddhas word for it. I realise now you probably didn't mean for me to do that either.
I have the feeling I might be off topic really here
